The company has now announced that anyone caught using its Amazon Marketplace to sell devices that "promote, facilitate or enable" illegal access to copyrighted TV and films for free will now have their accounts suspended.
"Any streaming media player or other device that violates this policy is prohibited from sale on Amazon."
Of course, this doesn't stop people from buying "clean" Kodi boxes, and then downloading the copyright infringing add-ons themselves.
The penalties for sellers are high - and could result in time behind bars.
In December 2016, Terry O'Reilly was sentenced to four years imprisonment for selling illegal set-top TV boxes, a prosecution brought by the Premier League with support from FACT.
Meanwhile in February, set-top boxes pre-loaded with Kodi streaming software were seized at the homes of the five suspects in Bolton, Bootle, Cheadle, Manchester and Rhyl.
It is believed the suspects made in the region of £250,000 selling the devices online.
"Kodi is open source software, and as long as the GPL (General Public License) is followed, you are welcome to do with it as you like," Kodi Product Manager Nathan Betzen told TorrentFreak last year.
